Sean was very helpful with planning our retic integration in order to avoid using filtered water through our convoluted setup. The installation was neat and professional and the end result has seen skin and taste benefits immediately.
Water from sink is like no other that I've drank. Water is so soft in the shower not worried about drying out my skin anymore.
Really good company to deal with, no sales man or pressure, great product, great price, quick easy installation, big filters that last, compared to some other company offerings.
Amazing service from Sean and a very reasonably priced system. Quick, precise and tidy install. Watermark certified filters so you get legitimate filters not some knockoffs.
Sean recently installed both a whole house water filtration system and a reverse osmosis system for me, and I couldn’t be happier with the result. From start to finish, he was professional, knowledgeable, and easy to deal with.
Sean recently installed a whole home filtration system for us. Throughout the entire process from initial contact to installation he was knowledgable, quick, professional and easy to deal with.
Calcium and magnesium from the limestone aquifers, chlorine for the long pipe network, and sediment from old mains. It ends up in your kettle, your shower screen, your hot water system, and on your skin. Read our Perth water guide.

Scott had our premium 1 micron whole-house system installed. Two months on, he talked us through what changed at home and why he chose a local plumber over the bigger companies.
I shopped around and I did look, probably three or four different companies.
He literally come out that day. He quoted straight away, got the quote that evening.
The cartridges were big and they last 15 months.
Quotes are Scott's own words from the video.

Straight answers from Sean, our licensed plumber.
Ask us anythingOur premium whole-house triple filter package is $2,845 including GST, fully installed. That's complete filtration for every tap, shower and appliance in your home, and it includes both colour-coded and stainless steel covers so the system blends in with your home's outdoor space. There are no hidden costs: the price is fully installed by qualified, licensed installers.
Our whole-house filters are changed every 15 months, much longer than some competitors' 6-month filters. You'll get a text message reminder when your filters are due, so there's nothing to keep track of.
No. Our whole-house system with a Puretec softener gives you both in one installation: clean, soft water throughout your home. It's what most Perth families need, because our water has both contamination and hardness issues.
It doesn't have to. Our package includes both colour-coded and stainless steel covers, and covers can be painted to match your brick or render, so the system blends in with your home.
No. Whole-house systems must be installed by a licensed plumber and should be installed to WaterMark standards. Professional installation ensures compliance and proper function, and it protects your warranty. All our installations are done by experienced, licensed plumbers.
